[R6RS] Scripts vs. S-expression library names (not)

[dyb at cs.indiana.edu]

I'm having second thoughts about the "loose" library and entry names.
How about:

  <script header> <script spec> <library>

or possibly

  <script header> <library> <script spec>

where

  <script header> -> #!/usr/bin/env scheme-script <line break> #!r6rs
  <script spec> -> (script <library name> <entry name>)

I know I just said it doesn't matter where #!r6rs appears, but I think
it's better to require it to appear just after (or logically as part of)
the header, before both the <script spec> and the <library>.
